Returns a new instance of IlvDiagrammerServletSupport.

Overrides:

createServletSupport in class IlvSDMServlet

createServletSupport

protected IlvSDMServletSupport createServletSupport(javax.servlet.ServletContext context)

Returns a new instance of IlvDiagrammerServletSupport.

Overrides:

createServletSupport in class IlvSDMServlet

Parameters:

context - The servlet context.

setDefaultProject

public void setDefaultProject(String project)

Sets the default project file. This method does not actually load the project file, it just sets the default style sheet and the default data source.

Loads a Diagrammer project file. This method actually loads the project in the diagrammer.servlet, and creates the diagram.

Parameters:

request - The request being processed.

project - The URL of the project file.

getDiagrammer

public IlvDiagrammer getDiagrammer(javax.servlet.http.HttpServletRequest request)

Returns the IlvDiagrammer object used to compute the diagram for a given request.

Parameters:
